Were fetal cells used in the COVID-19 vaccine’s development?
None of the COVID-19 vaccines contain any cells from aborted fetuses.
Something called fetal cell lines, which are different from actual fetal cells, were used in what is called a confirmation test for the Pfizer (Comirnaty) and Moderna (Spikevax) vaccines. The confirmation test was used to verify that these vaccines work, but they are not used in the production of the vaccines being administered to people.
Fetal cell lines have been grown in labs for decades. These cells have multiplied, creating generations of fetal cell lines. This means that the cells scientists use today no longer contain fetal tissue. Several religious groups and bioethics institutes have issued statements and guidance about the COVID-19 vaccines.
For example, The Vatican has issued clear guidance that permits Roman Catholics in good faith to receive COVID-19 vaccines that use fetal cell lines in development or production. Read the Vatican’s comments on the morality of receiving a COVID-19 vaccine.
We understand this topic is very sensitive and important for some, raising ethical and moral questions. We want everyone to feel like they are making a fully informed decision about getting a COVID-19 vaccine. We encourage anyone with concerns about the use of fetal cell lines in vaccine development to weigh the risks and benefits of the COVID-19 vaccines with their doctor.
